strengths and weaknesses

Question 1

• Difficult to control variables
• Difficult to replicate the same conditions of the study
• Ethical problems can arise

Answer 1

Field experiments

Question 2

• Works in natural setting
• Larger scale research
• Subjects are not influenced by the observations of the experiments

Answer 2

Field experiments

Question 3

• Used to study complex systems
• Compress a time frame, which allows to study the behavior of the system more quickly
• “What-if” questions can be tested and answered

Answer 3

Simulation

Question 4

• Model building requires deep knowledge of the field
• Time consuming and expensive
• May require specialized hardware and software tools

Answer 4

Simulation

Question 5

• Low development time
• Cost-effective
• Easy data collection and analysis using statistical methods
• Can reach high audiences
• High representativeness
• Not affected by the subjectivity of the researcher

Answer 5

Surveys

Question 6

• Reliability of data is very dependent on the quality of answers and on the survey’ structure
• Rigidity of the structure
• Don’t capture emotions, behavior and changes of emotions of respondents

Answer 6

Surveys

Question 7

• A lot of information and different domains can be explored
• Degree of association between two variables can be easily calculated
• No manipulation of behavior is required

Answer 7

Correlational study

Question 8

• No direct cause and effect can be inferred
• May lacks internal/external validity
• Doesn’t provide a conclusive reason for the existence of a correlation between two variables

Answer 8

Correlational study

Question 9

• Several statistical tests and techniques can be used
• A lot of information and different domains can be explored
• Technical rigor of the process

Answer 9

Multivariate analysis

Question 10

• Complex of the employed techniques
• Requires the use of specialized statistical software

Answer 10

Multivariate analysis

Question 11

indicated when a given topic is relatively unexplored and it becomes important to understand in detail a given phenomenon, while maintaining the environmental conditions in which it occurs

Answer 11

Observation

Question 12

very time-consuming method, which requires prior preparation and the availability of the researcher to visit the place where the event occurs

Sensitive method since the interpretation of the data is done exclusively by observer

Answer 12

Observation

Question 13

researcher can have an in-depth knowledge about the situation in analysis

Answer 13

Ethnography

Question 14

requires a huge investment in the researcher’s time and the results produced by the study can be very diverse and it can become difficult to extract precise and targeted conclusions

Answer 14

Ethnography

Question 15

allows researchers to have a depth perception about people and processes by understanding the behavior of people and their experiences. The collection of data is done on the field and it can occur over an extended period of time

Answer 15

Field research

Question 16

not easy to generalize this approach to a very large number of people or groups, and documenting observations may become a challenging process

Answer 16

Field research

Question 17

can provide a broader range of information more quickly and offer the opportunity to seek clarification

Answer 17

Focus groups

Question 18

can be hard to control and manage
can be difficult to encourage people to participate

Answer 18

Focus groups

Question 19

provide a mean to investigate complex situations with multiple variables under analysis, appealing for advancing a field’s knowledge base, a good opportunity for innovation and challenge current theoretical assumptions

Answer 19

Case studies

Question 20

Difficult to establish a cause-effect connection to reach conclusions and it can be hard to generalize

Answer 20

Case studies

Question 21

assessment method design to get and compare responses from all the interviews

can inquire about past experiences and/or proposed hypothetical situations

Answer 21

Structured interviews

Question 22

time consuming, they don’t have the same flexibility in the choice of the answers that are predefined

Answer 22

Structured interviews

Question 23

kind of unstructured, direct, and personal interview with each respondent

provide very rich information, and it offers the opportunity to ask follow-up questions, probe additional information, justify previous answers, and establish a connection between several topics

Answer 23

In-depth interviews

Question 24

time intensive, and it is not generalizable

Answer 24

In-depth interviews
